Capstone Technical Workshop

Present: Andrew, Tim, Sarah, Jacob, Glenn



Andrew presented the whole APS philosophy as used in LV2a

Here's a blurry picture of the power block diagram of LV2a's power system. Note the Avionics Power System (APS) with the Lithium Ion battery pack and power switches. Then notice the DC-DC converters scattered around - big ones for the RF power amplifiers, small ones on the nodes' front end.

Discussed CAN/Power connector used in LV2a and things we don't like about it

Here's a picture of the notes. The drawing is mostly of the old connector. Here's a link to the old connector:

Tim presented the SPS used on LV2a nodes

Here's the sketch of the new SPS block diagram (t's a composite of three shots). Note the repeat of the switching circuit, and the three outputs based on using a split inductor.
